Some 2021 F-150 vehicles equipped with automatic high beam control may experience the fog lamps flashing when the automatic high beam control feature is turned on, the fog lights are turned on and the vehicle is driven in dark conditions. This may be due to the software in the headlamp control module (HCM). To correct the condition, reprogram the HCM using the latest level of the appropriate Ford diagnostic scan tool. If the condition persists, refer to Workshop Manual, Section 417-01 and continue with normal diagnostics. For claiming, use causal part number 13K198 and applicable labor times from Section 10 of the Service Labor Times Standard (SLTS) Manual.
